Y BALING-PRESS.

SPECIFICATION forming part of Letters Patent No. 3771.942, datedFebruary 14, 1888.

Application filed April 3, 1886. Serial No. 197.652. (No model.)

.To all whom it may concern:

Be it known that 1, OWEN B. KINNARD, of Minneapolis, Hennepin county,Minnesota, have invented certain Improvements in Baling-Presses, ofwhich the following is a speciflcation.

This invention relates'to improvements in presses for baling hay andother brous material; and the object Ihave in view is to provide animproved means for operating the plunger of the press. f

rIhe invention consists,generally,in the construction and combinationhereinafter described, and particularly pointed out in the claim.

In the drawings forming a part of this specication, Figure 1 is a sideelevation of a portion of thepress, showing a portion ofthe plunger withthe means for operating th same. Fig. 2 is a plan of the same.

2 represents the frame-work of the machine, which may be of any suitableconstruction.

3 represents the plunger, which may be of any preferred construction,and reciprocates in a rectangular plunger-case, 5, intowhich the hay isfed through a suitable hopper, (not shown,) and from which it is forcedby the vplunger into the baling-chamber. The balingchamber may be of anyordinary or preferred construction. The plunger is connected by apitman, 7, with a crank, 9, that is journaled in a bearing, 11, upon asuitable support, 10. A'geanwheel, 13, is mounted upon a stud, 15, andis driven through a gear or pinion, 17, that engages therewith. Thepitman is secured to a suitable crank-pin, 19. One end of this pin issecured to the crank9 and the other is secured to asliding block,21,thatis mounted in a radial slot, 23, in the gear-wheel'. The gear 13 isturned by the pinion 17. The crank 9 is thereby turned on its axis, andthe pitman and plunger are reciprocated. The throw of the crank issuicient to move the 4block 21 back and forth in the slot 23. Power isapplied to the circumference of the gear-wheel, and its center forms thefulcrum, the Aradius of the gear being one arm of the lever throughwhich power is applied to the pitman and the portion ofthe radiusbetween the center andthe position of the crank-pin at any point intherevolution of the gear being, at that point, the other. The axis of thecrank 9 is on the side of the center of the gear 13 farthest from theplunger. Y

When the parts are inthe position shownin Fig. 1, and from this pointuntil the plunger begins to recede, the crank-pin is very near thecenter of the gear. The leverage is therefore very powerful, which givesthe plunger great force at the time when it is compressing the hay inthe bale. After the crank-pin passes below the centerit begins to movetoward the circumference of the wheel, giving to the plunger. a quickreturn movement. plunger has a quick movement in the first part of itsstroke, a slow movement with great power in the latter part thereof, anda quick return movement, as described, which is an especially desirablemovement for apress of this class.

I claim as my invention- The combination, in a baling-press,with thewheel having the radial slot 23, the crank 9, the crank-pin 19, to whichthe pitman is connected, and the block 2l, fitting in the slot 23 andhaving the crank-pin secured thereto,sub stantially as described.

The

reciprocating plunger and pitman, of the In testimony whereof I havehereuntoset my hand this 29th day of March, 1886.

OWEN B. KINNARD. In presence of A. C. PAUL, ALBERT HAINES.
